Biogas plants for
egg poultry farms

Yes, chicken manure is a highly efficient raw material for biogas production from chicken manure, but due to its high nitrogen content, it requires technological solutions to reduce ammonia levels. That is why the biogas plant design must take into account ammonium neutralisation systems to avoid reactor shutdown and loss of productivity.

A water scrubber with acid recirculation is an effective solution for gas phase purification, as it reduces the concentration of ammonia in biogas and protects gas equipment and upgrading systems. At the same time, it is important to understand that a scrubber does not solve the problem of ammonia in the substrate layer, where it directly affects the stability of biological processes in the reactor.
Co-fermentation is a key tool for comprehensive ammonia control. It involves mixing nitrogen-containing raw materials (manure, slurry, litter) with carbon substrates such as silage, pomace or distiller’s grains. This allows you to balance the C/N ratio, reduce the toxic effect of ammonia on methanogenic bacteria, and ensure a stable biogas yield.
The best result is achieved by combining biological solutions in the reactor (co-fermentation) and physical-chemical purification of the gas at the outlet.

On average, the yield is 90-130 m³ of biogas per tonne of laying hen manure and 150-190 m³ per tonne of broiler manure. The exact result depends on the birds’ diet, the moisture content of the manure and the fermentation temperature. The production of biogas from chicken manure requires a stable process, which we guarantee.

It is possible, and in many cases it is a sensible solution. Adding silage or pomace improves the carbon to nitrogen (C/N) balance, reduces the concentration of ammonium nitrogen in the substrate and stabilises the operation of the bioreactor.
It is important to note that water scrubbers only solve the problem of ammonia in the gas phase and do not affect its concentration in the substrate itself. In addition, a scrubber is not a “cheap” solution: it requires significant capital investment, ongoing operating costs for reagents, electricity and maintenance.
ANA-strip reactors can be used as an alternative or supplement, allowing the concentration of ammonium to be reduced directly in the liquid phase while producing mineral fertiliser. The choice of the optimal solution depends on the composition of the raw materials, the scale of the project and the availability of coenzymes.

It is a special module for purifying fermentation effluents. It captures ammonium and allows the production of ammonium sulphate, a valuable fertiliser. Installing such equipment not only avoids environmental risks but also provides a new source of income from the biogas plant.

Yes, we implement plants for biomethane production with subsequent purification and compression to EU standards. This allows biomethane to be exported to European networks through the RED II certification system.

The capacity of a biogas plant is determined not by the number of birds, but by the actual volume and characteristics of the manure, in particular its dry matter and organic matter content and the method of collection.
For reference: a poultry farm that generates approximately 10–12 thousand tonnes of manure per year can power a biogas plant with an electrical capacity of approximately 500 kW, provided that the raw materials are properly prepared and the supply is stable.
For each project, we perform an individual calculation, taking into account the type of poultry farming, litter moisture content, co-fermentation possibilities, and the selected energy utilisation model.

On average, 6–8 years. The period depends on the volume of biogas production, the financing model chosen, and additional income from fertilisers or biomethane.
